I know how stressful this is! I have spotted a lot this first trimester--for about 8 days starting at implantation, then stopped for a week, then for about another two weeks continuously. Mostly just really light brown discharge, but pink a couple of times. It made me a nervous wreck, although I felt better once I had an ultrasound (at 7 weeks, 3 days) and saw the heartbeat. My doc said that about 30 percent of women who go on to have normal, healthy pregnancies spot--in of itself it doesn't mean anything. It seems to have stopped (and hopefully will stay away now) but I'm stilled nervous whenever I wipe. Everyone told me to relax, and that didn't seem possible--but maybe you're better at relaxing than I was! Anyway, it sounds like you are fine. Take care of yourself, try not to worry.
